Title: X-ray polychrome film - for prodn of coloured x-ray pictures for easier diagnostic interpretation
IPC: G21K4/00
Filed: 1972-09-08
Abstract: The transparent carrier film is coated on the front face with a multiple layer of polychrome photo-material and on the rear face with a layer of reversible polychrome emulsion. The sub layers in both emulsions have differing colours and radiation sensitivities and enhanced contrast in the individual sub layers may be increased by the addition to those sub layers of phosphorescent or fluorescent materials with characteristic peak emission wavelengths, when excited, corresponding to the peak sensitivities of their associated layers. Alternatively, they may be cross linked in terms of peak wavelengths to different layers and used for multiple exposures to produce flicker effect pictures. Improved colour discrimination and resolution.
Patent FR-2207756-A1 (FR)
Title: Scintillator crystal prodn - using crystallization promoter in fine suspension
IPC: G01T1/202
Filed: 1972-11-30
Abstract: The crystallisation promoter, whose particle size is 325-80 Tyler mesh, is bound with an inert carrier liquid and applied to the selected surface of a carrier crystal for 0.5-5 hours, under temp. and pressure conditions such that random oriented, regular, but non epitaxial crystal growth takes place, the grown material having the same microscopic orientation as the mother crystal. The growth promoter is cleaned away mechanically after the predetermined growth period and the growth is further limited by ensuring complete freedom from moisture of the mother crystal face, thus preventing specular reflection. Diffuse reflection characteristic of grown material optimises performance.

Title: Hydraulic mould locking system for injection moulding machine - with a sleeve valve controlling high pressure flow
IPC: B29C45/67
Filed: 1973-11-20
Abstract: Mould traverse and locking system using ancillary low press. long stroke rams to traverse the mobile platen and an annular piston to accept the high press. thrust for holding the tool shut, where the annular piston moves in a chamber having a series of radial outlets near each end. The chamber is surrounded by a sleeve valve which can slide longitudinally between two posns. One posn. completes a hydraulic circuit between the outlet on opposite sides of the annular piston, allowing oil transfer during traversing of the mobile tool. The other posn admits oil to the high press. side of the piston while allowing the downstream oil to exhaust. The mechanism thus self-compensating for variations in overall tool depth and minimises the oil vol. swing. The system is used for rapid cycling machines.
Patent FR-2253306-A1 (FR)
Title: Regulated DC power supply - uses variable chopping rate for control transistors or thyristors
IPC: H02M3/158
Filed: 1973-11-30
Abstract: With a three-phase supply, the rectification is achieved by six diodes (1-5) whose outputs are connected to low-pass filters via the regulating thyristors or transistors. Output current (21) is measured as well as the output voltage (19). Both are fed to the regulator control (30). This control also receives a three-phase supply and, from this, three saturated amplifiers produce three square waveforms. These are integrated to form three triangular waveforms. These are integrated to form three triangular waveforms. A series of comparators, sensing the output current and voltage, provide clipping to select the peaks of the triangular waveforms and convert them to variable width pulses to control the thyristors. This system is economical and uses a simple control circuit.

Title: Transmission producing asymmetric sley motion - to provide a longer rest time for weft insertion
IPC: D03D49/60
Filed: 1975-03-13
Abstract: Special control device for a weaving loom comprising (a) elements, on >=1 side of the loom, for converting the rotary motion of a motor shaft into a reciprocating rectilinear movement, connected rotatably to a lever pivoted to a fixed support on the fixed loom structure and articulated to a rod, the opposite end of which is articulated to an oscillating sley of the loom at a point not coinciding with the pivot axis of the sley, whereby (b) the points of fixed support and articulation are in alignment when the sley is at that end of its oscillation at which the warp shed is open, while the lever rotates through an angle 180 degrees so that only one such posn. of alignment occurs. In contrast to the usual motion of the sley, a longer rest period is provided where the sley reverses its motion at the weft insertion position (shed open), than at the opposite end of its stroke, so that for the same effective weaving speed slower shuttle speeds ma be used or alternatively greater weaving rates can be achieved with the same shuttle speeds.

Title: Measuring electrically effect on skin of harmful exposures - using cationic membrane and electro-osmotic flux, simulating skin and perspiration
IPC: G01N27/447
Filed: 1975-05-14
Abstract: Appts. for measuring the effect of exposure to thermal, chemical or mechanical attack on the human skin makes use of the changes in the electrical field created in a cationic membrane subjected to electro-osmosis. The membrane closes one end of a cell, the other end of which is closed by a cover through which electrodes pass. The cell contains a soln. of KCl and hyaluronic acid (10-2M) in proportions similar to those in the skin. The membrane is subjected by electro-osmosis to a flow of water and anions similar to perspiration. The electric field created in its thickness is measured by gold electrodes. One is solid and lies against the inner surface, the other is a deposit of colloidal gold on the outer surface, several microns thick so that it does not affect the behaviour of the membrane. The field of the membrane, hydrated by electrolysis, varies when the membrane is subjected to attack. It is measured by a millivoltmeter connected to a recorder. The harmful effect of thermal, chemical or mechanical attack on a membrane can be measured electrically and this measurement can be directly related to the effect on the human skin. The size and weight of the appts. are such that detection of a point effect is feasible. The electrical measurements can be used to compare 1st an 2nd degree burns. Such attacks as exposure to nuclear explosion and the sun can be explored.

Abstract: The perpetual calendar consists of a series of small plaques (8) or mosaics having motifs on their front and rear faces. Each of the plaques (8) is mounted in a frame (2) so that they can pivot around an axis (9) formed in the front part of the frame. The fixed axes (9) are parallel to each other, each having along (16) transverse section, two diametrically opposed rounded surfaces (16). These rounded surfaces (16) are separated by two diametrically opposite flat parts (17). The plaques (8) thus have two stable pivoting positions defined by the two flats (17), parallel to the face of the frame.
